Hintergrund der ErfindungBackground of the invention
Die zurzeit serienmäßig zum Einsatz kommenden Hochdruckpumpen eines Common-Rail-Einspritzsystems weisen Exzenterwellen mit Gleitlagern auf. Insbesondere bei Hochdruckpumpen für Common-Rail-Diesel-Einspritzsysteme ergeben sich Lagerlebensdauerprobleme aus den erhöhten Belastungen durch desaxierte Riemeneinwirkungen sowie die zusätzlichen hohen radialen und axialen Beschleunigungen aus den Motordrehungleichförmigkeiten. Für derartige Hochdruckpumpen werden auch als Kugellager und/oder Nadellager ausgebildete Wälzlager genutzt, wobei Kugellager gegenüber Nadellagern einige Vorteile aufweisen, etwa den geringeren axialen Bauraum, die geringere Reibung im Betrieb, die geringere Geräuschemission und die Fähigkeit, auch Axialkräfte in gewissem Umfang übertragen zu können. Diese konventionellen Kugellager haben jedoch den Nachteil, dass sie bei vorgegebenem Durchmesser aufgrund der zu geringen Tragzahl sowie wegen eines zu geringen Schmiermittelraumes im Lager für erhöhte Last- und/oder Lebensdaueranforderungen weniger geeignet sind.The currently used as standard in high-pressure pumps a common-rail injection system have eccentric shafts with plain bearings. Especially for high-pressure pumps for common-rail diesel injection systems Camp life problems arise from the increased ones Strain from strained belt impacts and the additional loads high radial and axial accelerations from the engine rotational nonuniformities. For such high pressure pumps are also called ball bearings and / or needle bearing trained rolling bearings used, wherein Ball bearings have some advantages over needle bearings, about the smaller axial space, the lower friction during operation, the lower noise emission and the ability to also transmit axial forces to some extent to be able to. However, these conventional ball bearings have the disadvantage that they have a given diameter due to the too low load rating and because of too small lubricant space in the warehouse for increased load and / or service life requirements are less suitable.
Wie bei allen Anwendungen im Fahrzeugbau wird auch von einer Hochdruckpumpe für ein Common-Rail-Einspritzsystem und deren Drehlagerung gefordert, dass diese axial möglichst kurz baut und vergleichsweise große Radialkräfte sowie in geringerem Umfang auch Axialkräfte bei langer Lebensdauer übertragen kann.As In all applications in vehicle construction is also of a high pressure pump required for a common-rail injection system and its pivotal mounting, that this axially as short as possible and comparatively large radial forces and to a lesser extent also transmitted axial forces with a long service life can.
Aufgabe der ErfindungObject of the invention
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, bei einer Hochdruckpumpe eines Common-Rail-Einspritzsystems ein Wälzlager einzusetzen, das eine vergleichsweise lange Lebensdauer aufweist, für hohe Radialkräfte geeignet ist und in gewissem Umfang auch Axialkräfte übertragen kann.In front In this background, the invention is based on the object at to use a rolling bearing for a high pressure pump of a common rail injection system, which has a comparatively long life, for high radial forces is suitable and to a certain extent also Can transmit axial forces.
Zusammenfassung der ErfindungSummary of the invention
Die Lösung dieser Aufgabe besteht in der Verwendung mindestens eines ein- oder mehrreihigen Kugelrollenlagers in einer Hochdruckpumpe eines Common-Rail-Einspritzsystems.The Solution to this task is to use at least a single or multi-row ball roller bearing in a high-pressure pump a common-rail injection system.
Der Erfindung liegt die Erkenntnis zugrunde, dass ein Kugelrollenlager gegenüber einem konventionellen Kugellager bei ansonsten gleichen Abmessungen einen größeren Schmiermittelraum aufweist, der daher mit einer größeren Schmiermittelmenge befüllbar ist. Dies sorgt für eine Lebensdauerverlängerung bei einem relativ kleinen Axialplatzbedarf in einer Hochdruckpumpe eines Common-Rail-Einspritzsystems. Zudem können durch die Kugelrollen in gewissem Umfang auch Axialkräfte übertragen werden und diese weisen im Betrieb eine geringere Reibung auf als Nadellager.Of the Invention is based on the finding that a ball roller bearing compared to a conventional ball bearing with otherwise same dimensions a larger lubricant space has, therefore, filled with a larger amount of lubricant is. This ensures a lifetime extension at a relatively small Axialplatzbedarf in a high-pressure pump a common-rail injection system. In addition, through the ball rollers are also transmitted to some extent axial forces and these have a lower friction in operation than needle roller bearings.
Die Kugelrollen weisen jeweils von der Kugelform abweichend abgeflachte sowie parallel zueinander angeordnete Seitenflächen auf. Durch diesen Aufbau wird insbesondere erreicht, dass für die Wälzkörper ein geringerer axialer Bauraum als konventionell benötigt wird. Der so gewonnene axiale Bauraum wird bevorzugt als zusätzlicher Schmiermittelraum genutzt. Die verbesserte Schmiermittel- bzw. Fettversorgung erlaubt eine geringere Reibung, wodurch die Lebensdauer deutlich erhöht wird.The Ball rollers each have flattened from the spherical shape deviating as well as mutually parallel side surfaces. By this structure is achieved in particular that for the rolling elements a smaller axial space is needed as conventional. The thus obtained axial space is preferably used as additional lubricant space. The improved lubricant or grease supply allows one lower friction, which significantly increases the service life becomes.
Kugelrollenlager
sind an sich bekannt und in der
Im Vergleich zu einem bauraumgleichen Rillenkugellager ergibt sich durch die Verwendung eines Kugelrollenlagers eine Steigerung der Lagerlebensdauer durch Erhöhung der Kugelanzahl und eine Steigerung der Fettgebrauchsdauer durch Schaffung eines größeren Fettreservoirs. Ebenso ist es möglich, durch die Verwendung eines Kugelrollenlagers unter Beibehaltung der Lagerlebensdauer die Lagerherstellkosten durch Optimierung der Bauraumverhältnisse durch eine Verminderung des Bauraums in radialer und axialer Richtung herabzusetzen. Gegenüber Gleitlagern und Nadellagern lässt sich ferner durch die Herabsetzung der Reibungsverluste eine Kraftstoffersparnis erreichen.in the Comparison with a space-identical deep groove ball bearing results by using a ball roller bearing an increase in Bearing life by increasing the number of balls and a Increase fat life by creating a larger one Fat reservoirs. Likewise it is possible by the use a ball roller bearing while maintaining the bearing life the storage costs by optimizing the installation space by a reduction of the installation space in the radial and axial direction decrease. Compared to plain bearings and needle bearings can be Furthermore, by reducing the friction losses a fuel economy to reach.
Das ein- oder mehrreihige Kugelrollenlager lässt sich vorzugsweise zur ein- oder beidseitigen Lagerung einer Welle und/oder wenigstens eines Pumpenstößels, der an einem Exzenter der Welle oder einem Außenring des mit einem exzentrisch ausgebildeten Innenring des Kugelrollenlagers anliegt, verwenden, wobei das Kugelrollenlager wenigstens eine zum Wellenausgang gerichtete Dichtscheibe aufweisen kann und ein elektrischer Antrieb für die Hochdruckpumpe eines Common-Rail-Einspritzsystems vorgesehen sein kann.The single or multi-row ball roller bearing can be used for one or both sides bearing a shaft and / or at least one pump plunger which abuts an eccentric shaft or an outer ring of eccentrically formed with an inner ring of the ball roller bearing, wherein the ball roller bearing may have at least one directed to the shaft outlet sealing washer and an electric drive for the high pressure pump of a common rail injection system may be provided.
